 wherein the alarm device is configured to be detached from the aerial vehicle based on the second abnormality recognizer recognizing the abnormal situation by receiving a signal indicating a determination that the abnormal situation has occurred from the first abnormality recognizer. 
 
     
     
       12. An alarm device configured to be held on an aerial vehicle that is capable of flying in an unmanned manner, the aerial vehicle comprising a body and legs disposed on a lower portion of the body and configured to support the body at a time of landing, wherein the body is configured to accommodate a battery, and an aerial vehicle controller configured to control an unmanned flight of the aerial vehicle that is powered by the battery,
 the alarm device comprising an abnormality recognition part configured to, during the unmanned flight of the aerial vehicle, receive a signal from the aerial vehicle, and recognize, from the received signal, an abnormal situation in which a determination is made that it is difficult for the aerial vehicle to continue the unmanned flight, wherein 
 the alarm device is disposed on the lower portion of the body of the aerial vehicle and adjacent to the legs of the aerial vehicle, and 
 based on recognition of the abnormal situation by the abnormality recognition part during the unmanned flight of the aerial vehicle, the alarm device is detached from the aerial vehicle, descends prior to the aerial vehicle, and activates an alarm mechanism to output warning of abnormality to a neighborhood. 
 
     
     
       13. The alarm device according to  claim 12 , further comprising:
 a mounting part attachable to and detachable from the aerial vehicle, wherein 
 the mounting part is detached when the abnormality recognition part recognizes the abnormal situation. 
 
     
     
       14. An aerial vehicle capable of flying in an unmanned manner, the aerial vehicle comprising:
